Self-employment tax in North Carolina (and everywhere in the US) is 15.3% on the first portion of net earnings: 12.4% Social Security (capped at the annual wage base) plus 2.9% Medicare (no cap, plus 0.9% additional Medicare above $200,000 single). It is calculated on net earnings × 92.35% to mirror the FICA tax employees would pay. North Carolina does not levy a separate self-employment tax, but state income tax up to 3.99% still applies to net business income.

Yes. If you expect to owe at least $1,000 in federal tax after withholding, the IRS requires quarterly estimated payments (April, June, September, January). North Carolina also requires quarterly state estimated payments to avoid underpayment penalties; due dates generally mirror the federal schedule.

North Carolina is workable for freelancers, though state income tax up to 3.99% reduces take-home compared with no-income-tax states. Other factors matter: cost of living, sales tax on services (varies by state), health insurance market, and local business license costs. North Carolina's $410,000 median home price is also part of the calculus.

Common federal deductions for North Carolina self-employed filers include: home-office (simplified $5/sqft or actual expense method), health-insurance premium deduction (above-the-line), self-employment tax deduction (half of SE tax), retirement contributions (SEP-IRA, Solo 401(k)), business mileage (70¢/mile for 2026), startup costs (up to $5,000 first year), and the Qualified Business Income (QBI) deduction (up to 20% of qualified income, subject to thresholds). North Carolina generally conforms to most federal business deductions for state purposes, with state-specific add-backs.

On $100,000 gross 1099 income with $15,000 expenses, estimated total tax is $23,202.28 in North Carolina vs $20,559.10 in Tennessee. Tennessee comes out lower by about $2,643.17 per year for this scenario.
